This is what I get when following the Android build instructions. No APK is made. I have tried updating all the required dependencies in Termux but nothing changes. I have also tried using the builder app but that ends with the same error. Any idea what's going on here? I have built this port on Android in the past, but have since got a new device and am trying to build it again.

Exact same issue. Android 11 Oneplus 7 Pro

I found the solution (at least for compiling, game doesn't seem to run on my device.)

If you haven't already, add the x11 repo with pkg install x11-repo. Then install the mesa package.
